Here is a picture of my youngest son (Caper # 2). He is holding a typical 120 volt 25 watt light bulb in his left hand. In his right hand is a 1000 watt 120 volt mogul base light bulb that my uncle use to use in his photography business. He used it to light his models/subjects while he was on site taking pictures. I thought that you might like a glimpse of this bulb.

Picture one shows David holding the bulbs to give you a size difference between bulbs. Picture 2 shows that actual writing on top of the bulb.

My uncle use to be a commercial and model photographer back in the 60's and 70's. He used to have like a big umbrella with the buld on the inside to illuminate the face of the model. There wasn't HID lighting at this time except for fluorecent. (I believe) There use to be some outside light fixtures that would use these same bulbs. Then along came the HID lights and these big bulbs went the way of the T-Rex.
